Well, I finally put a crowbar in my wallet and bought a 2003 Odyssey. Sweet van, hopefully picking it up later this week. Of course now comes the question - what oil? It has the 3.5L 240HP SOHC V-6. Given how much they charged for it, I need the engine to be the last thing that goes, like 15 years from now Here's my idea: Run two 3750 mile intervals with the Honda 5w-20 oil to get things seated nicely, then switch to "real" synthetic and go 7500 mile/1 year intervals thereafter. I know that only analysis can confirm this plan, but I figured I'd get a "gut check" first. Has anyone actually seen the 0w-20 Mobil1? I was considering using that if I can find it to please the warrantee lawyers in case of a meltdown. I haven't gotten the van yet, but if the owner's manual allows 5w-30 maybe I'll just use Mobil1 5W-30 since it's so easy to get and is pretty close to 20wt anyway. Can any Honda owners out there tell me what your book says about 5W-30 vs 5W-20? Thanks!
